Abstract (en)

The invention relates to an apparatus for generating electricity from water, the apparatus being provided with a first and second master electrode. The electrodes defining a flow path allowing water to flow along the electrodes and the apparatus is constructed to alternately allow water with a relatively high ion concentration and water with a relatively low ion concentration to flow along the electrodes. The apparatus may be provided with a floating electrode located between the first and second master electrodes in the flow path. One of the master and floating electrodes may be provided with a selective ion barrier layer, the selective ion barrier layer being selectively impermeable for either anions or cations.
